The best outdoor spaces are a seamless blend between the man-made and the existing landscape. That's why This Old House landscape contractor Roger Cook chose native Goshen stone for this patio, nestled along the craggy Massachusetts coast in Manchester-by-the-Sea.

Close enough to dip a toe in at high tide, the seaside perch offers panoramic views of the inlet and boulder-strewn cliffs. Here's a look at Roger's method.
